1. Cyanide poisoning is fatal. This is because cyanide has this effect of the electron transport chan:
inhibits cytochrome oxidase
2. The precursor of the sugar-phosphate moieties in the de novo synthesis of both purine and primidine
ribose 5 phosphate
3. The highest reservoir of calories in muscle tissue is
proteins
4. Deficiency in the intake of carbohydrates and fats can lead to:
increase protein requirements
5. Gluconeogenesis is the major source blood sugar during _________
prolonged fasting
6. The receptor involved in the G-protein coupled signal transduction pathway:
Beta-adrenergic receptor
7. This is the mechanism of action by which PENICILLIN kills bacterial cells:
it covalently binds to the active site of the enzyme for cell wall synthesis
8. TRUE of Vitamin K
it functions as a cofactor to carboxylase that acts on glutamate residues of clotting factor precursors proteins
9. Kwashiorkor occurs when there is
lack of calories and protein in diet
10. Cancer can be attributed to mutation in the DNA. A mutation that converts an amino acid codon to a stop
nonsense
11. The process by which a polypeptides destination in the cell is determined by
signal peptides
12. The type of histones: uniquely associated with the linker DNA
H1
13. Cytidine is a _______
nucleoSIDE
14. TRUE about the salvage pathway of purine nucleotide synthesis is correct?
Deficiency of hypoxanthine-guanine phosphoribosyl transferase is the cause of Lesch-Nyan syndrome
15. ______ is the source of MOST blood glucose during starvation:
alanine
16. An individual who has fasted for more than 24 hours will have increased production of
glutamine and alanine
